Juvenile spider riding a bug—phoresy in Baltic amber?

Abstract

Phoretic dispersal of arachnids (e.g., Araneae, Pseudoscorpions, mites) clinging to insects (Coleoptera, Diptera, Hymenoptera etc.) are reported from extant species and fossil inclusions preserved in amber. A Baltic amber piece contains a piesmatid (Heteroptera, Piesmatidae) carrying a juvenile spider (Araneae, cf. Clubionidae) on its back. This is the first report of such an association between a bug and a spider and it is questioned herein, what might be the reason for the documented assemblage.
